KAK Retro Extended Flash Hider 5.56 NATO 1/2x28 Phosphate
The KAK Retro Extended Flash Hider brings the classic XM-177 Moderator profile to modern AR-15 builds, with a 6.15-inch overall length that extends a 10.5-inch barrel to legal non-NFA length when pinned and welded. Its 1/2x28 thread pitch fits 5.56 NATO barrels, and the heat-treated steel with a phosphate finish resists corrosion through hard use.
Milled flats simplify installation, and the pre-drilled 0.125-inch hole is ready for pin and weld work. Professional installation with pin and weld is required for compliance, making this a practical choice for builders who want legal barrel length without giving up the retro look.
